A new paper in the journal Nature Communications finds that a global irreversible solar tipping point may have passed where solar energy comes to dominate global electricity markets, thanks to technological trajectories set in motion by past policies. " FILE - Wind turbines operate as the sun rises at the Klettwitz Nord solar energy park near Klettwitz, Germany, Oct. (AP Photo/Matthias Schrader, File) NEW YORK (AP) — The global. . The world may have crossed a “tipping point” that will inevitably make solar power our main source of energy, new research suggests. The study, based on a data-driven model of technology and economics, finds that solar PV (photovoltaics) is likely to become the dominant power source before 2050 –. . The global switch to renewable energy has passed a “positive tipping point” where solar and wind power will become even cheaper and more widespread, according to two United Nations reports released Tuesday, describing a bright spot amid otherwise gloomy progress to curb climate change. Last year. . New research suggests that solar power is set to become the dominant energy source by 2050.
